Me & my wife stayed at Shin's place for 2 nights, we would loved to have stayed longer but unfortunately it was fully booked. The location is great on Sukhumvit 12, you're just off the main road so there isn't much noise in the evening but you're close enough to BTS stations (Nana & Asok) as well as the MRT (Sukhumvit) - all being a 10-15 minute walk. There's plenty to see & explore right on the doorstop, Benchakitti park is a 10 minute walk from Shin's, there's also a 7-11 at the top of the road.
The unit itself is really clean & quite spacious, the amenities are perfect for a short/long term stay (kettle, washing machine, wardrobe). The check-in & check-out process was super simple & we had no issues.
